I'm facing with an issue with S3FS -> S3PROXY connected to an OpenStack Swift - Keystone 3.0

Connection is working as expected.
We see that the system hang when creating file in container swift.

The system create object but do not allow to save it. System can list, read existing contents , but the creating through S3FS - S3proxy do not work. Furthermore , when we tried to try to create one, object is defined, but stay empty and from there we cannot anymore list the object in the container.

We see error message such as :
HTTP response code 500 was returned, slowing down

We can reproduce the problem

Launch the swift proxy ( s3proxy ) with the connector

s3proxy --properties /etc/s3proxy/swiftconnector

Run the mount access

s3fs -f -o url=http://127.0.0.1:8000 -o passwd_file=/etc/passwd-s3fs/swift -o use_path_request_style my_container /mnt/Pool/7/my_container/switchcontainer2/

When creating a new file, i receive a slowing down error message :
at org.gaul.s3proxy.S3ProxyHandlerJetty.handle(S3ProxyHandlerJetty.java:76) at org.gaul.shaded.org.eclipse.jetty.server.handler.HandlerWrapper.handle(HandlerWrapper.java:97) at org.gaul.shaded.org.eclipse.jetty.server.Server.handle(Server.java:499) at org.gaul.shaded.org.eclipse.jetty.server.HttpChannel.handle(HttpChannel.java:311) at org.gaul.shaded.org.eclipse.jetty.server.HttpConnection.onFillable(HttpConnection.java:258) at org.gaul.shaded.org.eclipse.jetty.io.AbstractConnection$2.run(AbstractConnection.java:544) at org.gaul.shaded.org.eclipse.jetty.util.thread.QueuedThreadPool.runJob(QueuedThreadPool.java:635) at org.gaul.shaded.org.eclipse.jetty.util.thread.QueuedThreadPool$3.run(QueuedThreadPool.java:555) at java.lang.Thread.run(Thread.java:748) 2021-04-26T09:26:36.772Z [INF] curl.cpp:RequestPerform(2347): HTTP response code 500 was returned, slowing down

We analyste the difference between the 2 files, first one good → second one not good
